EDVIN EDGECOMB, OF LIVERMORE FALLS, MAINE.

KEY-I-RING.

SPECIFICATION forming part of Letters Patent No. 306,595, dated October14, 1884b.

Application filed February 20, 1884. (No model.)

To all whom it may concern Be it known that l, EDWIN Enenconn, ofLivermore Falls, in the county of Androscoggin and State of Maine, haveinvented a new and Improved Key-Ring, of which the following is a full,clear, and exact description.

The object of my invention is to provide a key-ring on which the keyswill be locked, so that they cannot accidentally escape therefrom.

My invention consists of a key-ring having a wide opening in one sidethereof, and provided with a stud projecting from the opposite sidediametrically across the ring and centrally into the opening, where itis provided with three notched disks capable of being adjusted so thattheir notches will come in line to permit of the removal of a keythrough them.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is aside elevation, partly in section. Fig. 2 is a transversesection taken on the line a3 00, Fig. 1, looking toward the notcheddisks. Figs. 3, 4, and 5 are views of the inner faces of the notcheddisks. Fig. 6 is a diametrieal section of the series of disks.

The ring A has an opening, a, in one side thereof, and the metal of thering is thickened at each side of the opening to form a guard for thenotched disks.

From the side of the ring opposite the center of the opening a a stud,B, extends diametrically across the ring and projects into the center ofthe openin The stud B is reduced in diameter to receive a sleeve, 0,which carries the inner disk, I), whose inner surface is about even withthe inner surface of the ring.

Outside of the disk I) two disks, 0 d, are placed loosely on the stud B,and washers c are placed above and below the middle disk, 0. The entireseries of disks is retained on the stud by a guard, f, which partlycovers the outer disk and extends down on opposite sides of the seriesof disks. A washer or nut, g, surmounts the whole, and being secured byriveting or otherwise holds the several disks and washers on the stud B.The entire series of disks is of about the same thickness as the ring atthe sides of openinga, and their diameter is nearly sufficicnt to fillthe opening in the ring. Each disk has a notch, 71, of sufficient depthto receive the bow of an ordinary key. The inner disk, I), has a shortstud, i, projecting from its outer surface into the concave side of theadjoining disk 0, and in position to engage either of two radial ribs,0, extending from the center outward along the inner surface of the saiddisk 0. The second disk, 0, has on its outer surface a stud, 2", whichprojects into the concave side of the disk (I in position to engageeither of the two radial ribs (1 with which it is provided. When theinner disk, I), is turned in one direction, the stud Q7, projectingtherefrom, touches one of the ribs 0 of the disk 0 just as the notches hof the the two disks coincide. A continued rotation of disk I) carriesthe disk 0 along also until the pin i of the disk 0 touches one of theribs (1 on the under side of the outer disk, (I, which occurs just asthe notch h of that disk coincides with the notches of the two otherdisks, when the bow of the key may beinserted in the notches and all ofthe disks turned at once until the key can be either placed upon orremoved from the ring, as circumstances may require.

.vVhen the key has been placed on or removed from the ring in the mannerdescribed, the disks are turned in. the opposite direction, bringing thestuds projecting therefrom into contact with the other set of radialribs, breaking the coincidence of the notches h, and rendering itdifficult or impossible for a key to escape from the ring accidentally.

The disks 0 (2 may be pressed to shape, slotted, and the stop and ribs ic d be formed in them all in one operation and at a minimum cost.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a key-ring with two or more rev oluble notcheddisks held on a pivot within the opening thereof, and provided withhorizontal ribs and vertical pins, respectively, whereby the diskshaving the ribs may be revolved by the pins of the other disks, to bringtheir notches into alignment, substantially as set forth.
